Intelligent driving technology is developing rapidly on the fast lane, and autonomous vehicle must be fully tested and verified to be truly applied on a large scale. Safety Of The Intended Functionality (SOTIF) performance and reliability testing are crucial. However, most of the testing for SOTIF both domestically and internationally revolves around three major methods: simulation testing, closed field testing, and public road testing. These three methods all have their drawbacks, resulting in significant time and economic costs for complete testing. To solve this problem, this paper designs a test method for SOTIF performance and reliability with high coverage scenarios based on multi-level element simulation system. By building a scenario simulation system that covers four major scenario levels: road layer, environment layer, dynamic interaction layer, and information layer, high coverage reproduction of the test scenario is carried out in the laboratory environment. The system can not only achieve SOTIF performance test, but also carry out all-weather efficient verification of the reliability of automatic vehicle. The experimental results show that this method has the advantages of three traditional methods and can significantly improve testing efficiency.
